Problems solved by technology

The sterilizing effect of LED lights is related to its irradiation distance, but the storage items in the refrigerator are of different sizes and uneven heights, which makes the irradiation distance from the protruding dome-shaped LED lights to the surface of each storage item different, thus making sterilization and freshness preservation uneven effect

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0023] It should be understood that terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0024] like figure 1 and figure 2 As shown, the present invention provides an LED device for sterilization of a refrigerator, which includes an LED lamp 10 and a controller 20 . The LED lamp 10 includes several LED lamps 11 and sensors 12 arranged side by side and slidably connected to the inner top of the refrigerator 30 along the vertical direction. The LED lamp 11 is a blue light LED of a point light source, and is used for vertically illuminating the surface of the storage to sterilize and keep fresh. The sensor 12 is used to collect the real-time vertical distance informat...

Abstract

The invention discloses an LED device for refrigerator sterilization. The device comprises an LED lamp and controllers, wherein the LED lamp comprises multiple LED lamps and sensors which are disposedin parallel and are in slide connection to the top of the inner side of the refrigerator along a vertical direction; the controllers are in communication connection to the LED lamps and the sensors;the LED lamps are blue light LEDs which directly illuminate the surface of a stored object; the sensors are used to collect real-time vertical distance information between the LED lamps which are disposed in parallel with the sensors and the top end of the stored object, and are also used to send the information to the controllers; and according to the received real-time vertical distance information, the controllers send out first drive information which drives the LED lamps to get close to or stay far from the stored object along the vertical direction. The LED light supplementation device provided by the invention is characterized in that vertical irradiation distances between the LED lamps and the refrigerator stored object can be adjusted automatically; and uniform irradiation, sterilization and freshness maintenance can be achieved.

Description

technical field [0001] The invention relates to the technical field of refrigerator sterilization, and more specifically, the invention relates to an LED device for refrigerator sterilization. Background technique [0002] The device installed inside the refrigerator and sterilizes by lighting includes ultraviolet lamps and LED lamps. Ultraviolet lamps have been gradually eliminated because they are harmful to human eyes. Low-temperature storage of blue LED lamps can achieve antibacterial and fresh-keeping effects, and are increasingly used in refrigerator sterilization, fresh-keeping and lighting. [0003] In the prior art, most of the LED lights installed inside the refrigerator are protruding dome-shaped lights, which irradiate the stored items below to realize sterilization, preservation and illumination. The sterilizing effect of LED lights is related to its irradiation distance, but the storage items in the refrigerator are of different sizes and uneven heights, which...
